Silent Ender 3 PSU fan duct
thingiverse
I'm trying to avoid buying new fans for my Ender 3, so I've been searching Thingiverse for a simple and silent fan duct to keep my PSU cool. After not finding one that met my requirements, I decided to design one myself. This custom fan duct allows air to flow smoothly while blocking the initial sound due to its unique wave pattern. The wave pattern directs airflow in such a way that wind noise is minimized.
